My main suspension members are ready to be refinished and I need to decide which way to go.
The options seem to be:

1: POR15 (Good function but not original looking?)
2: Powder Coating (Too thick a coating and traps moister under chips)
3: Rattle Can (Not hard enough to be durable?)
4: Have body shop paint them black. (Expensive and what paint to use?)

I am going for the most original finish possible. I don't expect to be entering the car at Pebble Beach but want the parts to look as factory new as possible.

If anyone has had good success with a finish process I would appreciate hearing what it was.

Thanks.
